Get Phant:

You can use Phant directly from Sparkfun’s server, but you are limited to 100 data uploads in 15 minutes (one upload per 9 seconds).

You can also download Phant’s source code, modify it (like lifting the upload limitation), and install on your server. To do so you need to know Javascript and Node.Js. I have my own version that increases the limitation and enforces signin. You can get my version on Github (use with your own risk!) or take a look on data.modernblackhand.com.
